中文摘要：

在运用长周期水文模型模拟舒城县暴雨径流平均响应的基础上，结合临近研究区域的不同土地利用面源产出参数，估算了舒城县2000年土地利用变化的面源污染输出响应。结果表明，舒城县面源污染输出主要以氮的输出为主，主要输出源是耕地。土地利用变化对面源污染输出的响应差异主要受人类活动的影响。人类活动影响越强烈，面源污染输出越大。

英文摘要：

Based on the average response of rain - storm - flow which is simulated by the long - term hydrologic impact assessment and output index of non - point source pollution to land use near the county of Shueheng,the output of non - point source pollution on land - use in the district in 2000 was estimated. The results show that the largest output of non - point source pollution is nitrogen, the land - type of whicht is farmland. The output differences caused land - use are controlled by human activities. The stronger the impact of human activities, the larger the output of non - point source pollution.
